Logging 5.7 Release Notes

Before this update, when viewing logs within the OpenShift Container Platform web console, cached files caused the data to not refresh. With this update the bootstrap files are not cached, resolving the issue. (LOG-4100)

Before this update, the Loki Operator reset errors in a way that made identifying configuration problems difficult to troubleshoot. With this update, errors persist until the configuration error is resolved. (LOG-4156)

Before this update, the LokiStack ruler did not restart after changes were made to the RulerConfig custom resource (CR). With this update, the Loki Operator restarts the ruler pods after the RulerConfig CR is updated. (LOG-4161)

Before this update, the vector collector terminated unexpectedly when input match label values contained a / character within the ClusterLogForwarder. This update resolves the issue by quoting the match label, enabling the collector to start and collect logs. (LOG-4176)

Before this update, the Loki Operator terminated unexpectedly when a LokiStack CR defined tenant limits, but not global limits. With this update, the Loki Operator can process LokiStack CRs without global limits, resolving the issue. (LOG-4198)

Before this update, Fluentd did not send logs to an Elasticsearch cluster when the private key provided was passphrase-protected. With this update, Fluentd properly handles passphrase-protected private keys when establishing a connection with Elasticsearch. (LOG-4258)

Before this update, clusters with more than 8,000 namespaces caused Elasticsearch to reject queries because the list of namespaces was larger than the http.max_header_size setting. With this update, the default value for header size has been increased, resolving the issue. (LOG-4277)

Before this update, label values containing a / character within the ClusterLogForwarder CR would cause the collector to terminate unexpectedly. With this update, slashes are replaced with underscores, resolving the issue. (LOG-4095)

Before this update, the Cluster Logging Operator terminated unexpectedly when set to an unmanaged state. With this update, a check to ensure that the ClusterLogging resource is in the correct Management state before initiating the reconciliation of the ClusterLogForwarder CR, resolving the issue. (LOG-4177)

Before this update, when viewing logs within the OpenShift Container Platform web console, selecting a time range by dragging over the histogram didn’t work on the aggregated logs view inside the pod detail. With this update, the time range can be selected by dragging on the histogram in this view. (LOG-4108)

Before this update, when viewing logs within the OpenShift Container Platform web console, queries longer than 30 seconds timed out. With this update, the timeout value can be configured in the configmap/logging-view-plugin. (LOG-3498)

Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the more data available option loaded more log entries only the first time it was clicked. With this update, more entries are loaded with each click. (OU-188)

Before this update, when viewing logs within the OpenShift Container Platform web console, clicking the streaming option would only display the streaming logs message without showing the actual logs. With this update, both the message and the log stream are displayed correctly. (OU-166)

CVE-2023-28466

Before this update, it was not possible to delete the openshift-logging namespace directly due to the presence of a pending finalizer. With this update, the finalizer is no longer utilized, enabling direct deletion of the namespace. (LOG-3316)

Before this update, the run.sh script would display an incorrect chunk_limit_size value if it was changed according to the OpenShift Container Platform documentation. However, when setting the chunk_limit_size via the environment variable $BUFFER_SIZE_LIMIT, the script would show the correct value. With this update, the run.sh script now consistently displays the correct chunk_limit_size value in both scenarios. (LOG-3330)

Before this update, the OpenShift Container Platform web console’s logging view plugin did not allow for custom node placement or tolerations. This update adds the ability to define node placement and tolerations for the logging view plugin. (LOG-3749)

Before this update, the Cluster Logging Operator encountered an Unsupported Media Type exception when trying to send logs to DataDog via the Fluentd HTTP Plugin. With this update, users can seamlessly assign the content type for log forwarding by configuring the HTTP header Content-Type. The value provided is automatically assigned to the content_type parameter within the plugin, ensuring successful log transmission. (LOG-3784)

Before this update, when the detectMultilineErrors field was set to true in the ClusterLogForwarder custom resource (CR), PHP multi-line errors were recorded as separate log entries, causing the stack trace to be split across multiple messages. With this update, multi-line error detection for PHP is enabled, ensuring that the entire stack trace is included in a single log message. (LOG-3878)

Before this update, ClusterLogForwarder pipelines containing a space in their name caused the Vector collector pods to continuously crash. With this update, all spaces, dashes (-), and dots (.) in pipeline names are replaced with underscores (_). (LOG-3945)

Before this update, the log_forwarder_output metric did not include the http parameter. This update adds the missing parameter to the metric. (LOG-3997)

Before this update, Fluentd did not identify some multi-line JavaScript client exceptions when they ended with a colon. With this update, the Fluentd buffer name is prefixed with an underscore, resolving the issue. (LOG-4019)

Before this update, when configuring log forwarding to write to a Kafka output topic which matched a key in the payload, logs dropped due to an error. With this update, Fluentd’s buffer name has been prefixed with an underscore, resolving the issue.(LOG-4027)

Before this update, the LokiStack gateway returned label values for namespaces without applying the access rights of a user. With this update, the LokiStack gateway applies permissions to label value requests, resolving the issue. (LOG-4049)

Before this update, the Cluster Logging Operator API required a certificate to be provided by a secret when the tls.insecureSkipVerify option was set to true. With this update, the Cluster Logging Operator API no longer requires a certificate to be provided by a secret in such cases. The following configuration has been added to the Operator’s CR:

tls.verify_certificate = false
tls.verify_hostname = false

Before this update, the LokiStack route configuration caused queries running longer than 30 seconds to timeout. With this update, the LokiStack global and per-tenant queryTimeout settings affect the route timeout settings, resolving the issue. (LOG-4052)

Before this update, a prior fix to remove defaulting of the collection.type resulted in the Operator no longer honoring the deprecated specs for resource, node selections, and tolerations. This update modifies the Operator behavior to always prefer the collection.logs spec over those of collection. This varies from previous behavior that allowed using both the preferred fields and deprecated fields but would ignore the deprecated fields when collection.type was populated. (LOG-4185)

Before this update, the Vector log collector did not generate TLS configuration for forwarding logs to multiple Kafka brokers if the broker URLs were not specified in the output. With this update, TLS configuration is generated appropriately for multiple brokers. (LOG-4163)

Before this update, the option to enable passphrase for log forwarding to Kafka was unavailable. This limitation presented a security risk as it could potentially expose sensitive information. With this update, users now have a seamless option to enable passphrase for log forwarding to Kafka. (LOG-3314)

Before this update, Vector log collector did not honor the tlsSecurityProfile settings for outgoing TLS connections. After this update, Vector handles TLS connection settings appropriately. (LOG-4011)

Before this update, not all available output types were included in the log_forwarder_output_info metrics. With this update, metrics contain Splunk and Google Cloud Logging data which was missing previously. (LOG-4098)

Before this update, when follow_inodes was set to true, the Fluentd collector could crash on file rotation. With this update, the follow_inodes setting does not crash the collector. (LOG-4151)

Before this update, the Fluentd collector could incorrectly close files that should be watched because of how those files were tracked. With this update, the tracking parameters have been corrected. (LOG-4149)

Before this update, forwarding logs with the Vector collector and naming a pipeline in the ClusterLogForwarder instance audit, application or infrastructure resulted in collector pods staying in the CrashLoopBackOff state with the following error in the collector log:

ERROR vector::cli: Configuration error. error=redefinition of table transforms.audit for key transforms.audit

Before this update, when forwarding logs to a syslog destination with the Vector collector and setting the addLogSource flag to true, the following extra empty fields were added to the forwarded messages: namespace_name=, container_name=, and pod_name=. With this update, these fields are no longer added to journal logs. (LOG-4219)

Before this update, when a structuredTypeKey was not found, and a structuredTypeName was not specified, log messages were still parsed into structured object. With this update, parsing of logs is as expected. (LOG-4220)

Before this update, the presence of numerous noisy messages within the Cluster Logging Operator pod logs caused reduced log readability, and increased difficulty in identifying important system events. With this update, the issue is resolved by significantly reducing the noisy messages within Cluster Logging Operator pod logs. (LOG-3482)

Before this update, the API server would reset the value for the CollectorSpec.Type field to vector, even when the custom resource used a different value. This update removes the default for the CollectorSpec.Type field to restore the previous behavior. (LOG-4086)

Before this update, a time range could not be selected in the OpenShift Container Platform web console by clicking and dragging over the logs histogram. With this update, clicking and dragging can be used to successfully select a time range. (LOG-4501)

Before this update, clicking on the Show Resources link in the OpenShift Container Platform web console did not produce any effect. With this update, the issue is resolved by fixing the functionality of the "Show Resources" link to toggle the display of resources for each log entry. (LOG-3218)
